Simple Adjustable DC power supply(simple RPS)

Hi

It is my first post on electronics, post is concentrated on RPS. power supply is necessary for every electronics circuit but student or electronic hobbyist use traditional battery but it  cannot drive some circuit(current to drive ),  so u need variable regulated power supply for low cast, with simple design

1.   Step up down
2.    Rectifier
3.     Variable regulator

This circuit Output voltage will Adjustable between 1.2 V and 37 V, so you can connect  transformer range u want.

This circuit uses bridge Rectifier, u all know about this rectifier.

Coming to Adjustable regulator this circuit use LM317

• Output-Current In Excess of 1.5 A

• Output-Adjustable Between 1.2 V and 37 V

• Internal Thermal Overload Protection

• Internal Short-Circuit Current Limiting

To  Adjust output voltage by adjust 10k pot


Components:

• Diode 1N4001-4nos
• 1000uf
• 0.1uf
• 1uf
• LM317
• 1Kohms
• 20k pot
• transformer range u need (recommend 24v)

PCB design see  How to create PCB layout design in proteus8

I think u donot want give full description
you need any help comment below.

Trusted me guys its  100% working
